B=2.35 + 0.25x

c=1.75+0.40x

In the equations above, b and c represent the price per pound, in dollars, of beef and chicken, respectively, x weeks after July 1 of last summer. What was the price per pound of beef when it was equal to the price per pound of chicken?

A. 2.60

B. 2.85

C. 2.95

D. 3.35

D. 3.35

Step-by-step explanation:

First we need to form an equation and solve it to find the number of weeks when the prices were the same. Because the prices were the same we can say that b = c, and therefore form the equation:

2.35 + 0.25x = 1.75 + 0.4x - Now we nee to solve it and find x.

2.35 - 1.75 = 0.4x - 0.25x

0.6 = 0.15x

x = 0.6 : 0.15

x = 4 weeks

So now we substitute x into the equation for beef and find the price.

b = 2.35 + (0.25 * 4)

b = 2.35 + 1

b = $3.35 per pound
